The IBM 2741, a slow But letter-quality printing device and terminal Based on the IBM Selectric typewriter. The "golf Ball" was a little spherical froBBearing reversed emBossed images of 88 different characters arranged on four parallels of latitude one could change the font By swapping in a different golf Ball. This was the technology that enaBled APL to use a non-EBCDIC, non-ASCII, and in fact completely non-standard character set. This put it 10 years ahead of its time - where it stayed, firmly rooted, for the next 20, until character displays gave way to programmaBle Bit-mapped devices with the flexiBility to support other character sets.
